If you’re looking to upgrade or replace your tires, the term “700x38c” might have popped up. But what does it really mean in terms of tire size, performance, and compatibility? You’ve come to the right place for answers. Let’s break it down together, so you’ll know exactly what you’re dealing with when it comes to the 700x38c tire size in inches. Spoiler alert: this isn’t just about numbers—it’s about the ride quality and comfort you deserve.
What Does 700x38c Mean?
The “700x38c” size might sound a little technical, but let’s demystify it. Essentially, it’s a way to describe the tire’s size and dimension, giving you an idea of its fit and performance characteristics. Let’s break this down into more digestible chunks:
- 700: This refers to the nominal diameter of the tire in millimeters. The 700 size comes from the old French tire-sizing system, where “700” represents the approximate outer diameter. However, don’t get too caught up in the 700 number because it’s not the precise actual diameter—more of a category for size.
- 38: This number is the width of the tire in millimeters. A 38mm wide tire offers a nice balance between stability and rolling efficiency. It’s popular among commuters, gravel riders, and those who enjoy a comfortable ride.
- c: This denotes the French system’s width category. In this case, “c” refers to a middle width range, where “b” would be narrower, and “d” would be wider. Most modern 700c bikes use the “c” category.
700x38c Tire Size in Inches
Now, let’s convert this into inches to make it more accessible, especially if you’re used to the inch system. A 700x38c tire size in inches roughly translates to a tire that is:
- Diameter: About 27.5 inches
- Width: Approximately 1.5 inches
Quick Reference Table: 700x38c Size Conversion
| Metric Size | Inch Equivalent |
|---|---|
| 700x38c | 27.5 x 1.5 inches |
This tire size is perfect for those who want a balance between control, comfort, and efficiency. Whether you’re commuting, tackling light trails, or navigating city streets, the 700x38c tire hits a sweet spot for versatility.
Why Choose 700x38c Tires?
So, why would someone choose a 700x38c tire over other sizes? Let’s explore some of the benefits of this particular tire size:
1. Comfortable Ride
A 38mm width means a wider surface area, which provides better shock absorption compared to narrower tires. Whether you’re cruising over gravel paths or navigating pothole-ridden roads, the added volume allows the tire to absorb more of the impact, resulting in a smoother ride.
2. Versatility
700x38c tire size in inches are incredibly versatile. They’re suitable for gravel bikes, hybrid bikes, and even some touring bikes. They offer a good mix of speed and stability, making them ideal for mixed terrain—perfect if you like switching from pavement to dirt without changing your setup.
3. Better Stability
Compared to narrower tires (like 700x25c), the 700x38c provides more stability. This extra width improves balance and confidence, especially on less-than-ideal surfaces. Think of the difference between balancing on a tightrope versus a wide plank; the broader the base, the easier the ride.
4. Grip and Traction
The additional width and volume also mean more contact with the ground. For riders who face rainy conditions, dirt trails, or uneven urban streets, this means better grip and traction—key elements for staying safe and in control.
Compatibility: Is 700x38c Right for Your Bike?
Frame and Fork Clearance
One of the most crucial considerations when choosing new tires is making sure they’ll fit your current bike frame. Not all bikes are designed to accommodate 700x38c tires, especially if they have narrower frame or fork clearances. To check compatibility:
- Measure Clearance: Check the distance between the forks and stays on your bike. You’ll need at least a few extra millimeters on each side of the tire to allow for safe clearance.
- Brake Type: If you have rim brakes, ensure that they can reach around a wider tire. Disc brakes tend to offer more flexibility here.
Rim Width
Another compatibility aspect to consider is rim width. A 700x38c tire size in inches will generally fit well on rims that are between 17mm to 25mm internally. Using a tire that is too wide or too narrow for your rim can lead to performance issues and potential safety hazards.
Performance Characteristics of 700x38c Tires
Now that we understand the size and compatibility, let’s look at how these tires perform across different metrics like speed, comfort, and efficiency.
1. Speed vs. Comfort Trade-Off
700x38c tires are not the fastest when compared to narrow road tires like 700x25c or 700x28c, but they strike a great balance. The increased air volume makes them more comfortable, especially on long rides or rough surfaces, while still being capable of decent speed on pavement. For many riders, the slight trade-off in speed is well worth the gains in comfort and stability.
2. Tread Depth and Patterns
Tread is an important consideration depending on where you’ll be riding. 700x38c tire size in inches come in different tread patterns to suit different needs:
- Smooth Tread: Ideal for road riding, offering low rolling resistance and higher efficiency.
- Knobby Tread: Better for gravel paths and light trails. The added texture provides more grip but can slow you down on smooth roads.
3. Rolling Resistance
Rolling resistance refers to how easily a tire can roll along the ground. Generally, wider tires like 700x38c tend to have higher rolling resistance compared to narrower ones, but this is somewhat mitigated by running lower air pressure. The lower pressure improves comfort and keeps the tire in contact with uneven surfaces, providing a more stable ride overall.
Tips for Choosing the Right 700x38c Tire
1. Consider Your Riding Style
Are you an everyday commuter? Do you like weekend gravel rides? Different riding styles call for different tire characteristics:
- Commuters: Opt for tires with a puncture-resistant layer to reduce the risk of flats.
- Gravel Riders: Look for tires with a combination tread that provides good traction without sacrificing too much speed.
- Touring Cyclists: Durability is key. Look for reinforced sidewalls and a solid construction to withstand loaded touring conditions.
2. Tire Pressure
One of the great things about 700x38c tire size in inches is that they can be run at a lower pressure compared to narrower road tires. The lower pressure provides more comfort without sacrificing too much in terms of speed. A good range for these tires is typically between 50-70 PSI, but always check the manufacturer’s recommendation and experiment within that range to see what feels best.
3. Puncture Resistance
Nobody likes getting a flat. Fortunately, many 700x38c tire size in inches come with added features to help prevent punctures, like a Kevlar or nylon belt beneath the tread. While these features can slightly increase weight, the trade-off for peace of mind is often worth it—especially if your route takes you through less-than-pristine roads.
Pros and Cons of 700x38c Tires
Pros:
- Comfortable Ride: Great for absorbing road shock, making your ride smoother.
- Versatile: Suitable for multiple bike types, including hybrid, touring, and gravel.
- Stable: Wider contact patch improves balance and confidence.
Cons:
- Slower Compared to Narrower Tires: Increased rolling resistance may slow you down.
- Not Suitable for All Bikes: Requires sufficient frame and fork clearance.
- Heavier: Wider tires can weigh more, slightly affecting acceleration and climbing.
